1. When detected early, breast cancer is treated successfully 98 percent of the time. Researchers continue to make impressive gains in the detection, diagnosis, and treatment of breast cancer. For example, according to the Mayo Clinic, the radical mastectomy, once a standard procedure for women with breast cancer, is now rarely performed.<br />However, breast cancer in seniors remains a very potent disease that will only be eradicated if women follow the recommended schedule and undergo annual mammograms. Recent statistics suggest that women are skipping annual mammograms, the key procedure to screening.<br />The National Cancer Institute estimates there will be 180,510 new cases of breast cancer and 40,910 deaths from the disease in 2007. The number of new cases has increased every year for the past thirty years, though death from breast cancer has decreased slightly. Breast cancer remains the second leading cause of cancerous death after lung cancer. It is also the second most common cancer among women after non-melanoma skin cancer.<br />Like all cancers, breast cancer begins with abnormal cell growth. These “bad” cells develop too quickly and spread, or metastasize, throughout the breast, often entering lymph nodes located under the arm or even moving into other parts of the body.<br />There are several signs of potential breast cancer, including a bloody discharge from or retraction of the nipple; a change in the size or contour of the breast; and a flattening, redness, or pitting of skin over the breast. A lump in the breast remains the most common sign.<br />If a woman detects a lump, she should see her doctor; however, the Mayo Clinic recommends waiting through one menstrual cycle, as breast shape changes throughout the cycle.<br />The Importance of Screening<br />“I cannot stress enough the importance of early detection and screening,” states Dr. Constance Lehman, professor of radiology at the University of Washington School of Medicine and director of breast imaging at the Seattle Cancer Care Alliance.<br />Unfortunately, Lehman sees a disturbing decline in annual screenings.<br />“Cancer is affecting more and more women, yet they are screening less,” she says. “It could be due to the costs of an annual mammogram for women with low or no health insurance or because, with new technology like targeted MRIs, women feel that mammography is no longer effective.”<br />Lehman says clinicians may also be partially responsible. Some, including all major cancer research centers, recommend annual screenings but others suggest a biannual exam. Lehman, co-winner of the Second Annual Ladies’ Home Journal “Health Breakthrough Award,” remains unequivocal: “There is no ambiguity—women past the age of 40 should be screened every year.”<br />Risk Factors<br />Several primary risk factors are believed to increase the likelihood of breast cancer. However, it’s important to keep in mind that most people with one or even several of these risk factors do not get breast cancer.<br />The Mayo Clinic and National Cancer Institute list these primary risk factors:<br />• . . . . . . Age<br />• . . . . . . Chest radiation as a child<br />• . . . . . . Start of menarche before the age of 12<br />• . . . . . . Adolescent weight gain<br />• . . . . . . No pregnancy or late pregnancy (after 30)<br />• . . . . . . Lengthy use of oral contraceptives<br />• . . . . . . Post-menopausal weight gain<br />• . . . . . . Late menopause (after age of 50)<br />• . . . . . . Increased breast tissue density<br />Excessive exposure to estrogen, the hormone that promotes the appearance of female secondary sex characteristics, appears to be the leading factor in developing breast cancer. Exposure to a combination of estrogen and progesterone for over a four-year period also increases the risk of breast cancer. This is especially significant due to trends in estrogen therapies to stave off premenopausal syndrome and other maladies. The more recent reduction of hormone replacement therapy has perhaps led to the recent slight decline in breast cancer cases for women over 50. Lehman believes women over 50 should consult their physicians about the apparent risks of hormone replacement therapies, especially if they have a family history of cancer.<br />Secondary factors, including smoking, obesity, alcohol, family history, diet, and stress, are also significant. As with reducing the risk of all cancers, a healthy lifestyle, including a good diet, frequent exercise, and moderate stress, is recommended.<br />Genetics may also play a role in breast cancer. Even though less than 10 percent of the breast cancer cases are inherited, women with a family history of the disease have a much greater risk of breast (and ovarian) cancer.<br />Breast Cancer in Seniors<br />Eighty percent of all breast cancer occurs in women over 50, and 60 percent are found in women over 65. The chance that a woman will get breast cancer increases from 1-in-233 for a woman in her thirties, to a 1-in-8 chance for a woman in her eighties.<br />“The average age of diagnosis is 62,” says Dr. Julie Gralow, associate professor of medical oncology at the University of Washington School of Medicine and medical oncologist at the Seattle Cancer Care Alliance. “So the majority of women getting breast cancer are over the age of 50.”<br />Gralow is especially concerned about the lack of women over 70 years of age in clinical trials.<br />“There are several situations unique to our older patients. We find it difficult to determine the toxicity levels of chemotherapy,” she explains, “because we simply don’t have enough information. This is significant because older women tend to have more tumors and thus be more sensitive to estrogen receptor positivity; or they might avoid chemotherapy altogether.”<br />Lack of information is just one of several issues surrounding breast cancer in seniors. An obligation as routine as visiting the doctor can prove challenging if the patient cannot drive or does not have anyone to take her to the appointment. This is quite significant with cancer treatment, as the patient must make six-to-eight weeks of daily trips to the hospital for radiation therapies.<br />“Nausea and other side effects are often much more severe with older patients,” explains Gralow. “And insurance of oral medicine can be spotty, especially if the patient depends upon Medicare.”<br />Gralow also notes the possible tensions between family involvement and doctor-patient discretion.<br />“I need to know what the patient wants shared because we need to respect patient privacy while keeping the family informed. So, as with all medicine, we try to bring the patient and her family together for a meeting at the start of the treatment.”<br />Treatment<br />Once cancer has been detected, the patient’s team of doctors will determine its stage and publish a comprehensive report. This highly detailed report should include everything from locations and descriptions of each tissue sample to the patient’s clinical history with the disease so far, according to the nonprofit website breastcancer.org.<br />Breast cancer treatment varies according to the stage of the cancer, or number and range of the malignant cells. The treatment regimen will also vary by organization, another reason why it’s so important to get a second opinion during every stage of the cancer experience.<br />The four traditional treatments include:<br />• . . . . . . Surgery<br />• . . . . . . Radiation Therapy<br />• . . . . . . Chemotherapy<br />• . . . . . . Hormone Therapy<br />Surgery was considered the primary treatment for breast cancer for over 100 years. Only recently has this approach changed, as new first response therapies have evolved and doctors have begun to implement targeted treatment strategies in many cases. Surgery still remains an important option, however.<br />Lumpectomy is the least invasive surgical procedure, as only the tumor is removed. Lumpectomies are recommended when there is no sign of the cancer spreading to other sections of the breast or body. It is commonly followed by five-to-seven weeks of radiation therapy as a precaution.<br />There are three levels of mastectomy, or removal of the breast. Total mastectomy results in the complete removal of the breast. A modified radical mastectomy, the most common surgical procedure, includes removal of the breast and the auxiliary lymph nodes. Radical mastectomy, long the standard procedure, requires removal of the entire breast, underarm lymph nodes and chest wall beneath the breast. After the surgery, doctors examine samples from each tissue group to determine further treatment, though radiation therapy is a routine follow-up procedure.<br />Radiation therapy, the use of intense light rays to kill cancer cells, has a 50-70 percent chance of reducing recurrence, according to the National Cancer Institute. Though less uncomfortable than most patients realize, radiation kills cancer and healthy cells in its path.<br />“We are beginning to reduce the length and intensity of radiation treatments, because of the development and continued improvement of targeted therapies,” Gralow explains. “In general, we are trending toward less toxic, less invasive therapies.”<br />Chemotherapy is a systematic, or whole body, treatment designed to kill cancer cells that have spread to anywhere in the body. Chemotherapy attacks rapidly dividing cells, both cancer and healthy cells, though recent developments have worked to reduce the infamous side effects. It is important to note that every chemotherapy treatment regimen is unique and depend upon many factors including patient and family medical history, current health and numerous other factors.<br />Hormone therapy, the use of certain hormones that attack cancer cells, is a systematic treatment designed to rid the entire body of cancer. Doctors use drugs to inhibit estrogen or progesterone from developing breast cancer cell growth or, in some cases, turn off production of ovarian hormones.<br />Hormone therapy is commonly used when the patient is hormone-receptor positive. It can be used to lower risk of the cancer’s occurrence for women at high risk, to lower the risk of recurrence, to shrink a large tumor, or to treat advanced disease.<br />There is also a newly developed regimen called immune targeted therapy, which mimics natural antibodies that attack specific characteristics of the cancer cell. Targeted therapies are added to chemotherapy, though researchers are also developing techniques to reduce the intensity of chemotherapy and even potentially eliminating it from the treatment regimen.<br />Gralow and Lehman both believe ongoing developments in hormone and other new therapies will greatly change the treatment of breast cancer in the future. The National Cancer Institute describes several. For example, the removal of the sentinel lymph nodes, the first node where the tumor is likely to spread, would prove a less invasive technique to stem the spread of the cancer.<br />A combination of high dose chemotherapy and replacement of the destroyed cells with a stem cell transplant is also in development, though the technique is as yet unproven. Use of certain kinase inhibitors that block the signals that tumors require to grow are also under study.<br />“There are some exciting changes in how we approach treatment,” Lehman says, “So if you are diagnosed with breast cancer you should go to a medical center with an expert reputation.”<br />“And always get a second opinion for your treatment regimen,” she adds.<br />“We are personalizing breast cancer,” says Gralow. She points to genetic research that targets specific cancer genes as well as genomic profiling to assess cancer relapse risk, which can help to reduce the use of chemotherapy in patients.<br />Gralow includes several other examples of research breakthroughs, including the use of MRI screening to detect preinvasive cancers and the reduction by half from six to three weeks of the radiation sequence, as patients receive a higher dose for a shorter period. This would greatly help with older patients, for whom attending six-to-eight weeks of daily treatment often proves a challenge. New targeted drugs like Herceptin®, effective thus far in 20-25 percent of patients and displaying diminishing toxicity, is also leading to wholesale changes in treatment.<br />“The lack of volunteers in study groups remains a significant obstacle in the development of therapy success rates for older patients,” states Gralow. “I would encourage older women to enroll in these trials, as they often receive new therapies and important information otherwise unavailable.”<br />Link To Original Article: http://www.aplaceformom.com/senior-care-resources/articles/breast-cancer-in-seniors/<br />About Senior Helpers:<br />Senior Helpers provides many in-home, caregiving services for the elderly in Southeast Michigan.
